Specification of Letters Patent. Patented Blair. 26, 1918.

Applicationfiled July 10, 1915. Serial No. 39,177;

To all whom it may con ern:

Be it known that we, EDMOND RHnIMs and Leon AUSCI-IER, citizens of France, residing at 131 Avenue Malakofi", Paris, France, have invented new and useful Improvements in Sash-Operators, of which the following is a specification.

The present invention has for its object an improved system of opening and shutting window sashesor other panel-likemembers used for closing in any apertures, such for example as window openings of motor vehicles, of railway carriages or rooms, the improved system being particularly applicable to cases where the movements of the sashes or panels, when they are to be shifted, are of a rising and falling nature in a vertical lane.

P The invention will be described with reference to the accompanying diagrammatic drawing, which is given by way ofexample, and in which-- Figure 1 is an elevation of an arrangement according to the present invention.

Fig. 2 is a cross sectional elevation of the same arrangement.

The same reference letters denote the same parts in the two figures.

On inspecting these figures, it will be seen that the system in question is carried out in the following manner The'lower member 1 of the window sash or panel 2 which is to be shifted, carries two parts 3, 4 to which are connected, respectively, the ends of two cords or lifting bands 5, 6 whose other ends are fixed to two stationary points 7, 8 on one of the sides a of the aperture which is to be opened or closed by operating the sash'or panel 2.

i The cords 5, 6 each pass over a doubly grooved pulley 9 mounted on an oscillating lever 10, arranged as hereafter explained. The cords pass over a doubly grooved guide pulley 11 and then separate in a manner so that cord 5 is attached to the part 3 while cord 6 passes over a single grooved guide pulley 12 and is attached to part 4. The two guide'pulleys 11, 12, are mounted so as to be able to turn on their fixed supports 13, 14 mounted on the upper part b of the aperture or opening, and in a way that the parallel portions of the cords 5 and 6 which proceed from these pulleys to the pieces 3 and 4 respectively, keep a vertical position.

Lever 10, which constitutes the lever for operating the arrangement, is mounted so as to be able to oscillate through a certain angle a about an axis 15 at its lower end and mounted on the lower part c of the aperture opening. This lever is connected at 16 to one of the extremities of a connecting rod 17 whose other end is pivoted to a lever 18 capable of oscillating around a fixed axis 19 carried by a suitable piece 20 mounted on one of the sides cl of the aperture. The end of lever 18, opposite to that'connected to rod 17 is connected at 21, in any appropriate way, to one end of a spring 22 whose other end is attached at 23 to a threaded rod 24 with which engages a nut 25 that bears against a fixed stop 26, whereby the tension of the spring can be adjusted as desired.

Moreover, the upper part b of the aperture is furnished with a suitable opening to permit lever 10 to be displaced through the angle 05, so as to occupy either of its two extreme positions.

In the arrangement described it is easy to see that the displacement of lever 10, in one or other direction, causes an angular dis placement of pulley 9 which communicates to the parts 3 and 4 a rectilineal displace ment of an extent greater than that of pulley 9 but which can be easily determined in accordance with mechanical principles that need not be explained here.

It should be observed that in the general operation of the arrangement the spring 22 plays an important part. During the movement of the lever 10 to lower the window sash or panel 2, the spring acts as a brake, in consequence of the tensioning by the weight of the sash or panel acting through the lever 18. p

Inversely, during the movement of the lever corresponding to the raising of the sash or panel 2 the spring acts as an energy regenerator tending to facilitate the rising movement by diminishing the requisite effort on the handle 27 of the operating lever 10.

Having now particularly described and ascertained the nature of our said invention and in what manner the same is to be per formed, we declare that what we claim is 1. In a sash operator, the combination with a sash and a casing, of a pivotally mounted operating hand lever, a pulley carried thereon, a pair of flexible connections passing over said pulley and connected to the sash and to the casing, a second lever connected with the hand lever, and an adjustable spring connected to the secondmentioned lever and to the casing for coun terbalancing the sash.

2. In a sash operator, the combination With a sash and a casing of a pivotallymounted operating hand lever, a pulley carried thereon, a pair of flexible cords passing over said pulley and each connected at one end to the sash and at the other end to the casing, a second lever connected With the hand lever, and an adjustable means connected to the second-mentioned lever and to the casing, for counterbalancing the sash.

In testimony whereof We have signed our 15 names to this specification in the presence of two subscribing Witnesses. V
